Date night? Suggestions?

Women like to nibble and like a good display. I'd go for some expensive deli cut meats she isn't used to, a couple of different types of cheese (I like blue cheese but not the best for a summer field with bugs, a few varieties of smoked cheese is best). Also some fruit slices, again think of bugs. Dip is optional. And a few bottles of water and red grape juice. Lay out a big blanket, and if she asks if that's what gun fire sounds like in combat, stare off into the distance and say no.

Strawberries as long as she's not allergic water is really good that way it doesn't seem like you're trying to get her drunk unless you know what her favorite drink is. Maybe a fruit tray from a grocery store Kroger normally has it on clearance in the evenings something with maybe some broccoli and ranch apples with caramel sauce. Some nice flower bouquet would be nice too

Pillows? A blanket to sit on?

Pretty sure "Die Hard," is a Date Night Movie.

foldable chairs or a mat,some cushions and snacks ?
